At the same time, the company operates a variety of products of related iron and A573 grade 70 CS steel carbon plate steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained A573 grade 70 CS steel carbon plate ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
Delivery status: SA537Gr1, normalizing;SA537Gr2, quenching and tempering, the tempering temperature should not be lower than 595℃;SA537Gr3, quenching and tempering, the tempering temperature should not be lower than 620℃.
The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.
A573 grade 70 CS steel carbon plate, Wear-resistant steel plates are easy to overheat, so pay attention to heating temperature and holding time. It is recommended to heat up to 820 degrees for proper insulation. Tempering temperature: 320 degrees, sufficient time. Hardness: 45-48HRC. Good performance. Salt bath NaCl:BaCl=3:7 can be heated at a temperature of 820, time is 30 seconds/mm (mm refers to the effective thickness of the part), oil cooling. Tempering temperature is 280, air furnace time is 2 hours, and nitrate furnace time is 30 minutes.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A573 grade 70 CS steel carbon plate plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A573 grade 70 CS steel carbon plate industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
